Faculty Members

Perception for autonomous robotic manipulation and grasping; developing methods that are goal-directed, real-time and multi-modal such that they can provide meaningful feedback for execution and learning.

Communication of digital images, including compression and transmission of video over the Internet, digital watermarking to protect intellectual property, 3-D image analysis and synthesis, and architecture of multimedia systems.

Interaction between visual experience and the structure and function of the brain using a combination of direct, but non-invasive measures of the brain's electrical activity along with psychophysics to study how the brain processes visual images.

Efficient sampling and reconstruction techniques for discrete signals
Geometry and combinatorics for families of higher dimensional Bezier curves
Analysis and geometry of two-dimensional harmonic maps and their lifts to minimal surfaces

Spaceborne radar systems and the application of remote sensing data to problems in geophysics. His current emphasis is on interferometric radar for topographic and surface deformation studies of earthquakes, volcanoes, and global environmental problems.
